' SHIELD FOR, PORTABLE AGETYLENE-GAS LAMPE' monies.

Specification of Letters Patent.

Patented Apr. 141, mm.

To all 'ivlzom it may concern.

Be it known that 1, Armin L. HANsnN, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Shields for Portable Acetylone-Gas Lamps, of which the following is a specification.

My invention relates more particularly to lamps of this type which are used by miners. It is very frequently the case that where miners are working in pairs that the eyes which are hereunto annexed-and are a part of this specification, in which:

Figure 1 is a sideelevation of an acetylene gas lamp having my improved shield mounted thereon. Fig. 2 isa'front elevation of the same. Fig. 3 is a"1tront view of the reflector, showing theshield turned to protect the eyes of the Worker at the side of the user of the light. Fig.4; is a front elevation of, a modified form of my invention. Fig. 5 is a vertical section of the same.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the shield 1 is secured to the reflector .2 oil the lamp, which consists in this instance of a water chamber 3 and a carbid receptacle 4-, a burner tip 5 being provided in the center of the reflector 2.

The shield l, as shown in. Figs. 1, 2 and 3, is formed of an annular piece of metal providcd with an outwardly extending portion 12, which extends much farther out than the remaining portion of the shield.

The annular member, which preferably is slightly tiered, is secured to the body ofthe lamp by three spring clamps l3, 7 and 8, which, as shown, are secured to the slde wall of the shield by means rivets 9 or any foregoing ployed if desired.

The outer end of the fastening device is offset, as at 10, and the springiness of the metal forming the clamps 6, 7 and 8 is such that when sprung over the shoulder 11 formed by the reflector 2 joining'the body of the lamp, the shield will be securely held in posltlon, but at the same time it is free to be rotated to the position in Fig. 3 in which the outwardly extended portion 12 of the shield will effectually guard the eyes of the oper'at'or on that side of the user of the light.

Should the helper be working on the other side of the miner, it is a comparatively simple matter to rotate the shield in the other direction until the outwardly extended portion 12 is in the opposite position tofithat shown in Fig. 3, as the clamping members serve only to hold the shield in 'position, but do not interfere with its rotation.

other suitable form of fastening may be em- By arranging the clamping members as shown, in the event of the operator striking his lamp against a projection, instead of the shield being crushed, the spring clamps yield and the shield is detached from the body of the lamp without injury to either. This feature is especially desirable Where used in mines.

As shown in Figs. 41 and 5,'the shieldis provided with a concave portion 13, which is provided with a central opening 12 the edges of which are inturned, as at 15, and are adapted to engage the gas tube in which the burner tip is mounted. Four slots 16 are cut inthe concaveportion 13 of 'the shield where this type is used, this serving the double purpose of permitting the shield to be detached easily from the lamp by means of a blow in the event of striking a projection, as above referred to, and also serves to ailord suiiicient pressure due to the springiness of the material used to hold the shield in position. Where this typeof shield is employed the concave portion of the shield acts as the reflector or" the lamp.

The operation of the device will be fully understood by persons skilled in the art from the foregoing desoripti on,but although I have shown a specific form of lamp, I do not limit myself to this iornuclor my shield is applicable to any carbid lamp employing a reflector and a centrally disposed burner tip.

Having described my invention, What I means to detaeliably and rotatably secure regard as new and desire to secure by Letthe said shield to the reflector. P
